And now I'm going to respond to my own posting.  The thermometer
problem is TRIVIAL with a capital T.  Basically all you need to do is
define a Rect someplace (like in a resource), get the size of the rect
and modify rect.right as follows:

rect.right = rect.right * count / totalCount;

As count counts towards totalCount it sets the right side of the rect
to be larger and larger.  Then you just do PaintRect(&rect).  Don't
forget to do PenPat(gray) before doing the PaintRect.

Its a quick half-hour hack.
